Pick-by-Light is a paperless picking process.
For this purpose, each storage location is equipped with an electronic shelf display. This shelf display has at least one eye-catching light, and usually also a quantity indicator and a confirmation button.
The picker is informed of the place of withdrawal via a light signal (the eye-catching light of a shelf display). A quantity indicator next to the eye-catching light informs him about the number of articles to be removed. The withdrawal is confirmed via a confirmation button and the process is thus posted to the principal system.
